The fabric may be composed entirely of synthetic fibres or may be a blend of synthetic and natural fibres, e.g. polyester and cotton. A denier in the range of 40-150 is specified. As shown, the fabric from a roll 10 passes through the nip 12 between rollers 14, 16. Preferably, the roller 14 has a metallic surface and is heated, either by the passage of a heated fluid therethrough or by an electrical resistance therein, to a temperature of 105‹- 185‹C. The peripheral surface of the roller 16 may be formed by a cushioning material, e.g. compressed cotton or a plastics material. The roller 16 may also be heated. The journals for the rollers 14, 16 are adjusted to give a pressure at the nip 12 of 135-175 kiloponds per square centimeter. The peripheral velocity of the roller 14 is slightly greater than that of the roller 16 so that the surface of the roller 14 frictionally slips relative to the fabric. Immediately after leaving the nip 12, the fabric is cooled by blowing a gas, e.g. air, thereon through ducting 18 and which is at a temperature of 20‹-25‹C. The fabric is wound on a take-up roll 20 which is then repositioned, Fig. 2, at the entrance to a heating chamber 22 in which the temperature is maintained at 100‹-180‹C. As the fabric leaves the roll 20 it has a temperature of 75‹-155‹C. The fabric is re-wound on a roll 24. As it passes from the roll 20 to the roll 24, the fabric is subjected-to a tensional force only great enough to move it along the desired path.

Abstract: 1409728 Electrodepositable resin PPG INDUSTRIES Inc 27 Oct 1972 [28 Oct 1971 1 Dec 1971] 49605/72 Heading C3B An electrodepositable resin, prepared from a resin containing epoxy groups, contains amino groups, at least a portion of which are primary amino groups which may be blocked by ketimine groups, hydroxyl groups and blocked or capped isocyanate groups which are reactive with hydroxyl or amino groups at elevated temperature. There may be 0À5-2À0 latent urethane groups per hydroxyl group. The products may be obtained by reacting a polyglycidyl ether of a polyhydric phenol with a primary or secondary amine and a semi-capped organic polyisocyanate having an average of about one free NCO group per molecule. The capping may be achieved by reaction with an aliphatic, cycloaliphatic, alkoxyalkyl or aromatic alkyl monoalcohol, a tertiary hydroxylamine or an oxime. The ketimine blocked amine groups may be obtained from a diketimine derived from one mole of diethylenetriamine and 2 moles of methyl isobutyl ketone. Electrodepositable compositions may be prepared by acidifying, e.g. with glacial acetic acid. A polyurethane forming catalyst, e.g. dibutyl tin dilaurate, may also be present.

Abstract: 1453453 D.C.-D.C. converters BICOSA SOC DE RECHERCHES 24 Oct 1973 [26 Oct 1972 2 Oct 1973] 49651/73 Heading H2F [Also in Division H3] A D.C.-D.C. converter comprises an inductor 3 connected in the collector circuit of a transistor 2, the base of transistor being coupled via a direct current path to the collector of a further transistor 4 the base of which is coupled via a capacitor 6b to the collector of transistor 2. The collector voltage is rectified by a diode 21, the circuit including a voltage stabilizing arrangement. As described, a battery comprising two alkali-manganese cells turns on transistors 2, 4 and thus builds up current in inductor 3. When the current in inductor 3 has risen sufficiently, transistor 4 is turned off, turning off transistor 2 for a time depending on the time constant 6b, 7a. The resulting rise in voltage across inductor 3 is rectified at 21 and charges capacitor 20 until Zener diode 24 breaks down, triggering thyristor 23 and discharging capacitor 20 via the primary of transformer 22, feeding an electric fence. The output frequency is equal to the resonant frequency of transformer 22 and capacitor 20. Inductor 3 is preferably wound on a toroidal ferrite core. In Fig. 3 (not shown) a D.C. output is obtained across capacitor 20, which is stabilized by a Zener diode connected between the cathode of diode 21 and the base of transistor 4. In Fig. 1 (not shown) an NPN transistor is used at 4 having the emitter/collector electrodes transposed. The D.C. output voltage is stabilized by a Zener diode connected across capacitor 20. It is shown that by compensating for reduction in battery voltage, the system can double the effective life of the battery.

Abstract: 1,173,096. Disc record players. E. G. NORRIS. 6 Nov., 1967 [15 Nov., 1966], No. 50365/67. Heading G5R. Apparatus for use with a record which is rotated during playback comprises a tone arm, means supporting the tone arm in a fixed position adjacent the record during playback, a pick-up head supported by the arm for translational movement along the arm during playback, and head moving and control means including an elongated flexible drive member selectively engageable with the head and operative to move the head to a selected position along the arm. In the position of Fig. 1, where a lug 15A on a head 15 is not in contact with a leg 17B, the pickup head is free to be driven on rollers, along a leg 17A by engagement of the stylus 16 with the record groove during playback. The stylus is lifted clear of the record by rotating the U-shaped member 17 (14B) about leg 17A as axis, so that leg 17B moves downwards in slot 18A in housing 18 until an endless cord 30 in member 17 makes contact with lug 15A; leg 17B is slotted underneath for this purpose, Fig. 3. Rotation of member 17 is accomplished by moving a lever 20, which is connected to member 17 through a support 32, Fig. 4. In the latter position the head may be traversed along leg 17A by rotating lever 20 to drive the cord 30, Fig. 4. Member 17 may be raised or lowered slightly by rotating wheel 42, Fig. 4, and the assembly may be swung clear of the record by movement about post 35, Fig. 4. The head is not connected by wires to housing 18 or elsewhere, so that it may be lifted from leg 17A for attention or replacement. Output signals from the transducer are provided in the manner shown in Fig. 7. Head 15 incorporates two L-C circuits 65, 66 (one for each track of a stereophonic record), each tuned to a frequency near the frequency of one of two oscillators 54, 56. The head circuits 65, 66 are coupled to the oscillators 54, 56 by leg 17A and singleloop inductive sections 50A, 50B, so that the outputs of the oscillators are amplitudemodulated by the played-back signals. In Figs. 9, 9D, the endless cord 80 extends along one groove 79A, around the outer end, and back along another groove 79B, of a rod 79 which is rotatable within a single tubular member 77 having a long slot 77A in its underside. By counterclockwise rotation of rod 79, and consequent engagement of it with a hook 75A on the pickup head 75, the head may be tilted and the stylus consequently lifted; and in this position the head may be traversed along tube 77 by cord 80, also in contact with hook 75A. Circuitry for a reluctance-type stereophonic head is also described (Fig. 10, not shown); the head is intended for use with oscillators somewhat as shown in Fig. 7.
